在此设置字段中输入变压器。在100至140VAC、200至280VAC范围内的电压，或者可以以0.1VAC增量输入400至560VAC。600 Vac的设置也是可能的。
调节器感应电流（A）。该设置字段读取并显示电流的标称输出
为DECS-100提供B相发电机线路电流的变压器（CT）。此值（1或5）
对于固件版本低于1.12.01的装置，必须手动输入版本号。这两个只读版本号表示BESTCOMS软件版本和DECS-100嵌入式软件版本。版本号仅在通信时显示
在DECS-100和BESTCOMS之间建立。
样式号。三个只读样式编号字段表示电气特性和DECS-100的操作特征。只有在以下情况下通信时，才会显示样式号：建立了DECS-100和BESTCOMS。
发电机PT比。发电机感应变压器的比率输入该设置字段。这比率允许通过BESTCOMS显示的电压与实际发电机输出电压相匹配。A.可以以0.01的增量输入1比150的比率。
发电机CT比率。发电机B相电流互感器的比率输入该设置字段。
该比率允许DECS-100显示的电流与实际B相发电机输出相匹配现在的可以以0.1的增量输入1到3000的比率。
母线电压比。该设置字段用于输入母线电位传感变压器比。这个比率允许通过BESTCOMS显示总线电压。可以在0.01中输入1比150的比率增量。
SETTING DEFINITIONS
Each of the six setting groups has a corresponding BESTCOMS screen. The settings of each screen are categorized by one or more tabs. In the following paragraphs, settings are arranged and defined
according to the organization of the BESTCOMS screens and tabs.
System Configuration
The System Configuration screen consists of one tab labeled System Settings. Click the Configure
button to access the System Configuration screen or click Screens on the menu bar and click System Configuration.
System Settings
System settings are shown in Figure 5-6 and described in the following paragraphs.
Sensing Voltage. This setting is used to configure the DECS-100 for either single-phase or three-phase sensing voltage.
Limiter Mode. This setting enables and disables the excitation limiters. Overexcitation limiting (OEL) or underexcitation limiting (UEL) can be enabled independently, both can be enabled, or neither limiter enabled. OEL Type. This setting configures the overexcitation limiter as a summing point limiter or takeover-style limiter.
Generator Frequency. This setting is used to select a nominal system operating frequency of 50 hertz or 60 hertz.
Regulator Sensing Voltage (V). The nominal, ac generator voltage obtained from the generator sensing
transformer is entered in this setting field. Voltages within the ranges of 100 to 140 Vac, 200 to 280 Vac,
or 400 to 560 Vac may be entered in 0.1 Vac increments. A setting of 600 Vac is also possible.
Regulator Sensing Current (A). This setting field reads and displays the nominal output of the current
transformer (CT) that supplies the DECS-100 with B-phase generator line current. This value (1 or 5)
must be manually entered for units with a firmware version lower than 1.12.01. Version Numbers. These two read-only version numbers indicate the BESTCOMS software version and
the DECS-100 embedded software version. Version numbers are displayed only when communication
between the DECS-100 and BESTCOMS is established.
Style Number. The three, read-only style number fields indicate the electrical characteristics and
operational features of the DECS-100. the style number is displayed only when communication between
the DECS-100 and BESTCOMS is established.
Generator PT Ratio. The ratio of the generator sensing transformer is entered in this setting field. This
ratio allows the voltage displayed through BESTCOMS to match the actual generator output voltage. A
ratio of 1 to 150 may be entered in increments of 0.01.
Generator CT Ratio. The ratio of the generator B-phase current transformer is entered in this setting field.
This ratio allows the current displayed by the DECS-100 to match the actual B-phase generator output current. A ratio of 1 to 3,000 may be entered in increments of 0.1.
Bus PT Ratio. This setting field is used to enter the bus potential sensing transformer ratio. This ratio allows the bus voltage to be displayed through BESTCOMS. A ratio of 1 to 150 may be entered in 0.01 increments.
